Snowballs were a temporary weapon featured in Grand Theft Auto Online during the Festive Surprise and were once again released for the Festive Surprise 2015 edition. For the 2014 version, they were only available on 24th December, 31st December and 1st of January. For the 2015 version, they were available from December 23rd to December 26th and from December 30th and January 1st.
Snowballs can be gathered and stored three at a time by pressing D-pad Left when a player is unarmed in snowy weather. Nine Snowballs can be stored at a time and will disappear when swapping sessions or starting Jobs. They are stored in the thrown-items section of the Weapon Wheel.
Snowballs are thrown using the same animations as Grenades and can therefore also be tossed underarm, and from vehicles. On some surfaces, where a snowball is thrown, it will leave a powdery texture (e.g. on vehicles), snowballs can be used to break vehicle headlights and windows, and snowballs can also hit/kill police without getting a wanted star.
As expected from snowballs, performance is poor. Snowballs do a minimal amount of damage. Oddly enough, Snowballs are lethal, as three snowballs are required to kill a pedestrian, and more than 10 must be used to kill a player with full health. Hitting the head of a pedestrian/player has a chance to knock them down for a small amount time. Like the Ball from GTA V, the snowball is light and can be thrown far.
- The ability to pick snowballs from the ground and throw them was also used in a previous Rockstar game, Bully.
